PRODUCTION DATA
The MODE/S-CONF pin is an input with two functions. It can be used to customize the device behavior in two ways:
The device interprets this pin during its start-up sequence after the internal OTP readout and before it starts switching in soft start. If the device reads a HIGH or LOW level, dynamic mode change is active and PFM/PWM mode can be changed during operation. If the device reads a resistor value, there is no further interpretation during operation and the device mode or other configurations cannot be changed afterward.
